I have good sound coming from my AUX. It really depends on your MP3 files, if they are lossless quality, 320kpbs, 128kpbs, etc etc. All my music is above 320kbps at least so I never experience any problems with my AUX and my Logic7. Some songs sound fantastic!

Also, it might also be your AUX cable. If you buy a cheap one for a few bucks the sound quality will definitely lack, not as noticeable as your MP3 file quality but still nevertheless present. Get yourself a decent AUX cable and start looking for 320kbps or higher MP3 files.

My aux sounds incredible. I really appreciate how in my car I can have my iPod be at a 100% volume and the quality is perfect. In other cars the driver asks for your iPod volume to be at 60-70% in order to sound good

Do not put the volume all the way up on your phone and youll be fine Had the same problem.

Hey, I'm using a monster cable from my beats by Dre. The sound is okay, its not crappy or anything but I just feel using a CD gives a lot more of crisper sound. Have you guys tried listening to a song on a CD compared to aux and turned the volume all the way up. You can def. hear the difference.

I find that Aux usually sounds better than bluetooth, but BT is sure more convienent. As I'm hosed and have no USB or anything, I have to start the ipod manually. A bit of a pain, but it does sound ok.

Bluetooth I can understand having worse quality because its a wireless connection. What i don't get is why CD quality > Aux quality. It should def be the other way around especially because CD players in cars have been around since the 90s.

it's the proverbial garbage in, garbage out.....for example, you should be going from the 30 pin connector of a iPod, not the headphone jack, so that your input is line level. It's a shame that we didn't get USB ports back in 2007....

Well, a CD would sound better than aux in most cases because a CD's recording is in lossless quality (true quality the song was recorded in), most people have crappy music files that are less than 320kbps so unless your audio files are lossless quality, the CD will sound better.

Yup. And coming out of the headphone jack isn't so good, but such is life.

Yeah, that is true too. So if you guys really want better audio from your iPhone/iPod, consider an LOD. It's a cable with a 30 pin connector and 3.5mm. It bypasses the amp in the iPhone/iPod and plays the music through the DAC, and that gives you a better signal. But if you don't have at least 320kbps or lossless files, don't bother.

MP3 files (and other audio files) are compressed. This often causes lower fidelity. I'm not sure of the current file formats and whether they've changed much in the last few years (Probably?), but here's an authority on some of the technical differences:

Do they have LOD cables for iphone 5 out yet?

I googled it and it seems like they havent made them yet?

Nope, not yet. Only the older devices that use the 30 pin connector but I'm sure there will be one for the iPhone 5 sooner or later. But keep in mind that they are extremely short because 99% of the people who use it connect it to an amp for a portable setup.
